【答案】【导语】木文讲述一个女孩从幻想“著名未来”到接受平凡但快乐生活的转变，强调行动比空

想重要。

1.句意：每个人都有梦想，我也不例外。

hobbies爱好；stories故事；dreams梦想；interests兴趣。开头在讨论未来设想，后文提到“bigdreams”，

因此“梦想”最合适。故选C。

2.句意：有时，我无法停止思考我将会是什么样子。

thinking思考;learning学习；hearing听;waiting等待。根据"aboutwhatIwillbelike”可知,此处指“无

法停止思考未来会是什么样子”，故选A。

3.句意：如果我每天练习钢琴，也许我会成为一名著名的钢琴家。

violin小提琴；piano钢琴；guitar吉他；drums鼓。后文明确提到“famouspianist”和“practicingthe

piano”，因此“钢琴”正确。故选B。

4.句意：当我长大了，我意识到我只是一个普通的女孩。

gotup起床；wokeup醒来；lookedup抬头看；grewup长大。根据"IrealizedthatIwasjustacommongirl."

可知，“随着长大”，作者意识到自己只是个普通女孩，表示成长过程中的认知变化。故选D。

5.句意：我不可能在全世界成名。

necessary必要的；important重要的；impossible不可能的；unhappy不快乐的。前文强调44commongirl”，

因此成为世界闻名“不可能”最合理。故选C。

6.句意：然而，现在我对未来有了不同的看法。

health健康;future未来;world世界;plan计划。根据“Intenyears,ImightbeaworkerinasmallcompanyM

并结合全文核心主题是“未来”，此处表示对未来的新看法。故选B。

7.句意：我很忙，但我仍然有时间写博客。

serious严肃的；famous著名的；aciive活跃的；busy忙碌的。后文“butIslillhavetime”表明虽然“忙

碌”，但有空闲时间做其他事。故选D。

8.句意：我仍然在练习钢琴，音乐使我的家温暖。

work工作；music音乐;blog博客;money金钱。根据"Iamstillpracticingthepianoandthe”可知，前文

在谈练习钢琴，因此“音乐”能使家温暖，符合语境。故选B。

9.句意：有远大的梦想是件好事，但行动比语言更重要。

words单词；answers答案；experiences经历；minds思想。actionsarcmoreimportantthanwords“行动比语

言更重要”，此处强调实践而非空想。故选A。

10.句意：如果梦想遥不可及，那就亳无意义。

believe相信；improve改善；reach达到；expect期望。此处表达“梦想太远而无法达到“，reach符合语境。

故选C。

11.句意：很难预测未来会是什么样子，因为世界变化很快，许多事情我们无法控制。

face面对；understand理解；save拯救；predict预测。根据“whatthefuturewillbelikebecausetheworldis

changingfaslandmanythingsarecutofourcontrol（控制）.”可知，后文解释“世界变化快"，因此“预测未

来”很难。故选D。

12.句意：很少有人会成为世界著名的，但我们仍然可以做很多事情。

All所有的；Many许多的；Few很少的；No没有。此处表达“很少有人会世界闻名"，与“butwecan

stilldoalol”形成对比。故选C。

13.句意：从底层到顶层，我们应该永不停止为美好的未来而奋斗。

fighting战斗;waiting等待;asking询问;caring关心。根据"weshouldneverstop…forabrightfuture."可

知，此处表达“为美好木来而奋斗”，fighting符合语境，表示为未来而奋斗。故选A。

14.句意：虽然有些人在生活中有问题，但他们会努力克服这些问题，努力变得更好。

exhibitions展览；differences差异；problems问题；resolutions决议。后文“overcomethem"指克服“问

题"，problems符合逻辑。故选C。

15.句意：他们也是生活的赢家。

reporters记者；winners赢家；planners策划者；singers歌手。根据前文“theyworkhardtoovercome（克服）

ihcmandtrytobecomebetter.”可知，克服困难的人是“生活的赢家”，winners符合语境。故选B。

5.What'sthestructureofthispassage?

【答案】本文是一篇说明文，主要讲述了未来天气可能发生的变化以及这些变化带来的影响。

I.细节理解题。根据文章“SomecountriesinAfricaaregoingtobecomeverydryallyearround,andpeople

canhardlyfindfoodandwaler.（非洲的一些国家将全年变得非常干旱，人们几乎找不到食物和水。）”可

知，在非洲一些国家，人们找食物和水会很困难，故选

2.词句猜测题。根据文章“Nooneknowshowmuchwarmeritisgoingtobe,butscientistssaythatthechange

isgoingtobeatleast2°C.TheysaythattheiceintheArctic（北极）isgoingtomeltinthenextyearsandalotof

theanimalstherearegoingtodie.（没人知道会变暖多少，但科学家说这种变化至少会达到2摄氏度。他们

说北极的冰在未来几年将会融化，那里的很多动物将会死亡。）"，结合常识可知，气温升高，冰会变成

水，所以“mell”意思是变成水，故选A。

3.推理判断题。根据文章“Thereisalsogoingtobemorewaterinthesea,socitiesneartheseaaregoingto

disappear.（海里的水也会更多，所以沿海城市将会消失。）”可推知，住在一些沿海城市的人们将不得不

离开他们的家，故选Do

4.主旨大意题。文章开篇提到没人知道未来天气什么样，但很多人认为会有一些不同，接着从气温、降

水、北极冰、飓风和台风等方面讲述未来天气的变化，所以主要是关于未来天气的变化，故选D。

5.篇章结构题。文章第一段总述未来天气会有变化；第二、三、四段分别从不同方面阐述未来天气变化

及影响；第五段总结呼吁大家保护地球，是“总一分一总”结构，与选项A的结构相符，故选A。
